Branching fractions and direct CP asymmetries of charmless decay modes at the Tevatron
We present new CDF results on the branching fractions and time-integrated
direct CP asymmetries for and decay modes into pairs of
charmless charged hadrons (pion or kaon). The data set for this update amounts
to 1 fb of collisions at . We report
the first observation of the mode and a
measurement of its branching fraction and direct CP asymmetry. We also observe
for the first time two charmless decays of -baryon: and .Comment: Proceedings for Beauty 2006, Sept. 25-29 at Oxford University, to be

Updated measurements of hadronic B decays at CDF
The CDF experiment at the Tevatron collider established that
extensive and detailed exploration of the --quark dynamics is possible in
hadron collisions, with results competitive and supplementary to those from
colliders. This provides a rich, and highly rewarding program that has
currently reached full maturity. In the following I report some recent results
on hadronic decays: the evidence for the charmless annihilation decay mode
, and the first reconstruction in hadron collisions of the
suppressed decays and .Comment: 5 pages,2 figures, proceedings for EPS-HEP 2011. To be published in

B Physics at the TeVatron
The CDF and D\O\ experiments at the Tevatron collider established
that extensive and detailed exploration of the --quark dynamics is possible
in hadron collisions, with results competitive and supplementary to those from
colliders. This provides a rich, and highly rewarding program that is
currently reaching full maturity. I report a few recent world-leading results
on rare decays, CP-violation in mixing, penguin decays, and
charm physics.Comment: 5 pages, 1 figure, proceedings for IFAE2011. To be published in the

B Physics at the Tevatron
The Fermilab Tevatron offers unique opportunities to perform measurements of
the heavier b-hadrons that are not accessible at the Y(4S) resonance. In this
summary, we describe most important heavy flavor results from DO and CDF
collaborations and we discuss prospects for future measurements, that could
reveal New Physics before the start-up of the Large Hadron Collider (LHC)
CP and charge asymmetries at CDF
We present CDF results on the branching fractions and time-integrated direct
CP asymmetries for B0 and B0s decay modes into pairs of charmless charged
hadrons (pions or kaons). We report also the first observation of B0s->DsK mode
and the measurement of its branching fraction.Comment: Proceedings of The 2007 Europhysics Conference on High Energy Physics

Measurement of CP Violation in
Charm physics has played all along a central role in particle physics,
however the level of attention on it has tremendously increased in the last
years because of the observation of "fast" flavour oscillations
and because of very recent observed hints of CP violation. While in the past
these would have been unambiguously interpreted as signs of New Physics, the
revisitation of theoretical expectations, prompted by the latest experimental
measurements, makes the picture not clear. This brief review covers the current
status of CP-violating measurements in the system, both on the
experimental and theoretical side.Comment: 17 pages, 6 figures, 3 tables. Accepted by Modern Physics Letters A
